Engine cutting out at high rpm acts like not getting fuel tryed replacing fuel filter no change in running still will not change gears unless pump pedal alot. A mechanic told me before this to try putting rubbing alchol in tank. wont do that again. its was burning fuel out exhaust white smoke. any ideas what else it might be whan it was smoking it ran good now just cut out after adding alchol

Could also be a warped cylinder head, especially if you've been driving it that way for a while.
If you are noticing a higher than normal temperature indication, this is also indicative of a blown head gasket, warped cylinder head, or both. If your coolant levels seem to be dropping faster than normal it can mean that you're leaking it into the engine. Or, it can be that you have a coolant leak which caused you to overheat, and then blew the head gasket. It's something of a "chicken or the egg" situation.
The best way to determine if this is the case is to change your oil again and inspect it. If it looks like "milkshake," you have coolant mixing with the oil.

its a pvc problem had the same thing in my car when driving slow a little piece in the pvc is clogged and the smoke instead of coming out slowly comes out alot cuz the pressure gets built up

SOURCE: white smoke coming from exhaust when accelerating

This is usually an indication of a bad head gasket.I gasket. The white smoke is the coolant leaking out of the engine and winding up in the oil passages, due to a bad head gasket. To confirm this,
1. check oil. Is level increased, or milky appearance?
2. Is coolant level dropping, but u don't see any signs of leaks?
The above indicates a bad head gasket, causing the white smoke u describe. Let me know how u make out.

SOURCE: not accelerating and letting white smoke out exhaust

it sounds like the engine coolant is leaking into the combustion chambers most likely due to a leaky head gasket or a cracked cylinder head and will cause loose of power in acceleration

Then i think i'd be dumping some soapy water on the intake gaskets checking for leaks. ANd wiggle the **** out of all vacuum hoses. ( you probably did that) And if there aren't any, your cam could be tired. You got a tough one there. Hard to figure with a keyboard.
